B. Fixed fee for Company B is greater than Company A

Step-by-step explanation:

Company A:

A(n) = $0.99 + $0.25n

The function above is given in slope-intercept form, A(n) = mx + b (rewritten as A(n) = b + mx)

The unit rate (m) = per minute fee = $0.25

Fixed fee (b) = $0.99)

Company B: let's find the fixed fee (b), which is the y-intercept.

The y-intercept is the point on the y-axis where the line intercepts the y-axis.

If we draw a straight line, we would observe that the y-intercept (b) would be between 1.20 and 1.40.

Therefore, fixed fee for Company B would be between $1.2 and $1.4. this is greater than the fixed fee for Company A, which is $0.99.

Therefore, the statement that must be true is:

B. Fixed fee for Company B is greater than Company A

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
